fo @ZZ whom` it infr/,7j concern:

Beit known that I, JOHN CoNNnLL, of Rochester, NewYork, have invented anIniproved Machine for Lapping Barrel-Hoops, of

which t-he following is a specification, reference being had to the accompanying drawings.

My Vinvention relates to an improved machine for lapping hoops for barrel-s, kegs, &c.

'1 and it consists in the combination, with a reciprocating knife, of a recessed shear-block provided with a stop and guide by which the action of the knife on the hoop is controlled, y

'.head, of two knives and the above-mentioned devices arranged and adapted to produce the proper bevels on each end of the hoop, all as hereinafter more, fully described and specified.

My ilnproved lappingmachine is representv yed in the accompanying drawings, in which Figure l is a side elevation. Fig. 2 is a plan view. Fig'. 3 is afront view. Fig. 4 is a vertical section on the line a; m, Fig. l. Fig. 5 is aA plan view of the shear-blocks. Fig.` 6 is a Fig. 7 is aseotion on the line z z, Fig. 1. Fig. 8 represents one of the strippers detached. Fig. 9 is an end view of the same. A

In the; accompanying drawings, representing my improved machine for lapping hoops for barrels, kegs, &c., A is the frame of the machine; B, the reciprocating arm which carries the knife C. D is the shear-block, and E the crank-shaft by which the knife is operated. F is the guide, and G the spring-guard,.

and I-I the stripper. A

The frame A is formed of any suitable shape to afford at one end support for the shear block or blocks, and at the other for the-pivotal attachment thereto of thercciprocating arm B. In the ldrawings I have represented the arm as pivoted between the projecting jaws I I of the frame, being sustainedtherein by the piv? ots a a, which are arranged so that compensation can be made for wear. On one side of the frame is attached the bracket J,which sup ports in suitable bearings the crank-shaft E, carrying the tight and loose pulleys K K', by which power is applied to the machine. A brace, L, ties the frame together and affords a point of attachnrent for thebracket near theinside bearing of the crank-shaft. A crank, c, Figs. l. and 4, attached to the inner end ofthe crank-shaft, is fitted with boxes b b, which slide 7 in a slot formedin the extension N ofthe bar B,

so that the latter receives Va reciprocating motion from the rotation of the crank. rIhe slot for theboxes b bis formed by boltin g into the exten sion N a suitable cap, d. It will be observed that as the crankshaft E rotates in. the direction indicated by thearrow -in Fig. l a quick upward or return stroke is given to the bar B, carrying the knife C, whileon the downstrokr, at which time the cutting operation is performed, the power is applied to the best advantage.

rIhe fore or vibrating end of the arm B is guided in suitable ways, O 0', attached tothe frame and connected together at their upper' ends. In order to provide for wear of these ways, the arrangement represented in Fig. 7

may be adopted, in which the slides f f are attached to a lng on the arm B by t-he adjusting-screws g g', provided with jam-nuts.

The shear-block D is fastened to the arni A by `bolts passing through a flange, h, on its lower edge, Fig. 5. It is provided with a recess, z', Fig.V 5, which is tapering or wedgeshaped,as seen from above. The knife C passes up and down close to the outer or right-hand side of the shearblock in Fig. 5, and the recess is made of the same shape as is desired to be given to the hoop at the end of the lapping operation. inserted in the recess in the shear-block, shavvings are removed from the side thereof by the stroke or strokes of the knife on anoblique line, ntil the'end of the hoop arrives against the stop Z at the inner end ofthe recess.` This may be accomplished by oney or more strokes of the knife, according to the adjustment given 9 to the guide F, as hereinafter described. The flat side of the hoop toward its end is thus tapered Vor lapped down to the desired form, and each hoop acted on\by the in achine will be reduced to the same shape, the lap being The, end of the hoop being leo uniformly produced on all the hoops subjected to the operation of the machine.

The reciprocating movement of the bar A, carrying the knife C up and down close to the side of the shear-block, is represented in Fig. l by the full and dotted lines. As the knife C has its beveled or cutting-edge set at an angle with the shear-block, the shavings are removed from the hoop by a draw or slicing eut, which facilitates the lapping operation and prevents the splitting or splintering of the hoop.

In order to prevent the hoop from being carried upward by the rise of theknife,a stripper, H, is secured to the shear-block in Fig. 6. The 'form of the stripper is shown in Fig. 8, which represents the same as seen from the outside, and in Fig. 9, which represents it as seen from the front of the machine. rlhe stripper may be attached directly to the top of the shear-block; but in order to provide for adjusting it vertically, I prefer to attach it by a flange to the inside of the shear-block, as shown in the drawings. In Fig. 5 the stripper is represented by dotted lines.

The guide F, which projects over the narrow end of the recess, is fastened to the reciprocating arm A and travels up and down with it. The distance between the guide F and the side of the shear-block may be adjusted by placing liners or washers between its inner surface and the arm. The guide is made of a suitable beveled or curved form, so as to. perform the function of preventing the introduction of the hoop too far into the recess until its side has been reduced by the knife. This will be readily understood by an examination of Fig. 5. The outer edge of the end of the hoop strikes against the inner inclined surface of the guide, and is by it held against `the vertical side of the shear-block until it has been thinned bythe knife. Vhen the lapping operation has been completed, the end of the hoop strikes against the stop Z, so that each hoop is lapped or tapered on the same angle and left the same thickness at the end. The guide F also prevents a crooked hoop from turning outward too far into the path of the knife. The guide may be constructed to yield slightly when the hoop is introduced into the recess.

The guard G, which is attached to the reciprocating part carrying the knife, is preferably made slightly elastic or yielding, and operates to hold the hoop in the proper relation with the shear-block.

`In order to provide for lapping the hoop on one end and for giving it the proper taper or bevel on the point at the other, I place on the opposite side of the arm the knife C, recessed shear-block D, guide F, guard G',

provide two machines.

and stripper II, which parts are arranged to operate in a manner similar to that already described, except that the recess in the shearblock is made of a form suitable to .produce the bevel on the point. I am thus enabled in a single machine to perform the operations for which it would otherwise be necessary to The operator introduces one end of the hoop into the recessed shear-block 011 one side, and after the hoop has been acted on therein reverses it and subjects its other end to the knife working in connection with thc other shear-block. In front of each of the shear-blocks may b e placed the sockets 11. n, Fig. 3, by which the hoop is guided into the recesses.

It is obvious that any other mode of giving the requisite reciprocating motion to the knife arm or head, carrying the knife C, ma)7 be adopted.

I claim-- 1. The combination of the reciprocating knife C, the recessed shear-block D, provided with the stop Z, and the guide F, and suitable connecting mechanism adapted to support the shear-block and to impart reciprocating motion to the knife, substantially as described.

2. rlhe combination of the reciprocating knife C, the recessed shear-block D, provided with stop Z, and the guard G, and suitable connecting mechanism adapted to support the shear-block and to impart reciprocating motion to the knife, substantially as described.

3. The combination of the reciprocating knife G, the recessed shear-block D, provided with stop Z, guide F, and guard G, and suitable connecting mechanism adapted to support the shear-block and to impart reciprocating motion to the knife, substantially as described.

4. The combination of the reciprocating knife C, the recessed shear-block D, provided with stop Z, guide F, and the stripper H, and suitable connecting mechanism adapted tosupport the shear-block and to impart reciprocating motion to the knife, substantially as described.

5. In combination with a single reciprocating knife-head, the knives C C', recessed shearblocks D D', provided with stops Z Z, and the guides F F, adapted and arranged to produce the proper bevel on each end of the hoop, and suitable connecting mechanism adapted to support the shear-block and to impart reciprocating motion to the knife, substantially as and for the purposes described.
